The Study and Design of the Filter Bag Efficiency Control Set Using Arduino

The objectives of this research were to study and design a filter bag efficiency control set using Arduino that could function as a real-time alert system. The device consisted of dust measurement sensors located at two different spots and a NodeMCU control board. The lab was simulated using a transparent acrylic box, and two experiments were conducted. There were two methods used in Experiment 1, and the results of the second method with an installed filter bag and operating blower showed to be more efficient than the first one as it could reduce the amount of dust down to 12 µg/m³. In Experiment 2, talcum powder was utilized as the dust. The amount of dust passing through the blower into the bag varied in accordance with that inside the box. When the filter bag was full (at 1710 s [= 1,000 µg/m³]), the amount of dust increased during the ongoing experiment due to the lower efficiency of the bag. When the amount of dust surpassed the standard amount of 120 µg/m³ (at 2520 s), a red warning light appeared, indicating that the filter bag had to be immediately replaced with a new one.
